Real vs. Replica Comparison: Can the Clean Rolex Gray Rubber Daytona 4130 Movement Beat BT Factory?

The Rolex Daytona model is produced by Clean Factory with a solid 904L stainless steel case, standard case diameter and 7750 automatic chronograph movement architecture. It is among the most successful 1:1 super clone watch reviews on the market, with its sapphire crystal AR coating glass, original case tolerances and detailed workmanship.
Clean/Clean Rolex 116519 Daytona with Cement Gray Rubber Strap — Features of this 116519
1: Two cement gray Daytonas of the same model were purchased and molded. One was disassembled and measured, the other was kept for spare and sample comparison. One of them is now completely discarded, leaving only an intact dial fragment.
2: Features of the dial. This gray shade of cement gray was achieved by vacuum PVD coating, not colored by ordinary paint spraying. The advantage of PVD is that the coating layer can be kept in the range of 2-4 microns. In this way, the sun pattern at the bottom is not obscured. In ordinary paint spraying, the thickness is at least over 100 microns, that is, 1-2 reins thick; The color also becomes unstable and easily covers the sun pattern. In addition, the black sun pattern in the middle of the chronograph sub-dials and the CD pattern on the edge were removed from the mold exactly in line with the original. Below are detailed comparison images.
3: Hour markers have been completely renewed. The flat surface part was made flat enough, while the rounded corners were retained on the side surface; It was completely faithful to the original.
4: Glass issue. The original glass is not of high transparency, because it is a flat glass, it retains fingerprints very easily. Therefore, if the glass is too transparent, it looks fake. In the future, maybe we will switch to high-transparency glass, after all, customers love it; This may be our last resistance.
5: Since the case is a precious metal model, there are 750 and St. Marks on the four corners of the bottom surface. Bernard dog head stamp. In this section, this time, efforts were made to ensure fidelity. How similar it is, there are detailed comparison images below. The only thing missing is St. A tuft of dog hair on the head of a Bernard dog; We cannot do this for now. This is also considered a deficiency.
6: The ears on both sides of the case are produced separately. Compared to the ordinary 116500 steel case model, this is undoubtedly where the cost increases the most. The original was completely disassembled and reproduced exactly. They are perfectly interchangeable.
7: Clean rubber belt is used in the rubber belt part. Not just for fun. There are detailed comparison images below.
8: AR buckle is also used in the buckle part of the rubber strap. The opening and closing feeling and details are the same as the steel bracelet.
Clean does things surprisingly slowly, but we produce each piece with heart and care; We do not look at official catalog images and crudely imitate them. This time, we plan to release only a cement gray model. Because from now on, we will add real-replica comparison images to every color we release to show how much care we pay for the Daytona model. I hope everyone can wait patiently. Because each of the future models will be a quality product. We should point out that the unit price will be slightly higher than its peers in the industry; This is an evaluation that varies from person to person. I hope all watch lovers can buy the watch they like most when choosing a product; Even if that watch is not Clean production.
Since the new colors of the Panda Daytona came out, the gray Daytona has also exploded! Finding a watch for the original is nearly impossible; It is also very popular in the replica market! Previously, Clean maintained its leading position in the industry with the Rolex Daytona black-and-white panda model, and was highly appreciated by watch enthusiasts with its extremely high fidelity and stable 4130 movement. Nowadays, after the V2 upgraded version, Clean has reached its full perfection in terms of workmanship and has eliminated the defects. Watch lovers who love Rolex replicas, especially Daytona, can also consider Clean with peace of mind! The latest Rolex Daytona gray model also built on this success! The images below are comparison with the original. The Daytona rivalry is really heating up right now; Clean's Daytona has been pretty much taken over by BT Factory. The only way left is to attract more orders with continuous improvements or comparison images. I personally don't feel much for these current so-called official comparisons; After all, every company is the same, everyone says their product is good, this is human nature. Clean claims to produce a set of comparison images for each model; I'm personally quite curious. But friends who will buy precious metal models should also be careful: weight is a serious problem, after all, the density of precious metals is much higher than steel. In fact, now, both Clean and BT, the two companies are really close to each other. As for N Factory, which used to be prominent, it is really a bit outdated compared to these two current companies...
Previously, he also talked about the comparison of BT with the old version of Clean and N Factory; Those interested can look back: “Detailed review: BT Factory Rolex Daytona 4130 movement, comparison with Clean and N Factory, which one to choose?”
How is the Quality of Clean Rolex 4130 Gray Rubber Daytona Compared to the Original?
The same sapphire glass, ceramic bezel and 904L stainless steel case and strap are used as before. In terms of materials, this Daytona also chose 904 steel. After all, in today's conditions, the question posed by many watch enthusiasts, "why isn't platinum material used?" is not valid. First, if platinum material is used, the price becomes very high. In replica watches, it is still necessary to stay closer to the general consumer understanding. Of course, there is a certain amount of customization on the market, but I don't really recommend buying such things. There's no need to spend a few tens of thousands on a replica. Of course, this is just an evaluation!

First of all, when we look at the general appearance, the gray tone of the dial is the same as the original; It gives a glow effect in different lights, which is a big point of improvement. Unlike the dead, lifeless surface of BT Factory, which is obvious at a glance as fake, Clean has done a truly faithful job; It largely recreates the original both visually and tactilely.
In terms of dimensions, it is the same as before: thickness 12.4 mm. Case diameter is 38.5 mm, measured only by the ceramic bezel mouth; This data is the same as the original and can be used interchangeably with the original.

The center shaft of the hour and minute hands of the three secondary dials is very close to the original. In addition, the workmanship of the hands is different from the previous one: the two sides are slightly inclined downwards, that is, there is a curve; This gives the eye a stronger sense of three-dimensionality. This effect is not visible in the photo, but it can be seen in reality.

When we look at the dial details by magnifying it several times, the font printing is also quite three-dimensional. All hour markers are machined with rounded corners and a mirror polish is applied; When viewed as a whole, it looks very textured and is extremely shiny, especially when light falls on it. Extremely consistent with the original, almost interchangeable! The lume fill of the hour markers is a faithful light green and matches the fill color of the hour and minute hands.


In terms of the case, the material of the original is white gold; In order to reduce costs, Clean can only produce it from 904L stainless steel, which is very close to the color of white gold. It is very difficult to distinguish the difference with the naked eye, but there is a difference in weight.

As for the crown, the three small dots under the crown crown are large in the middle and small on the two sides; conforms to the original.



A classic closed design is also used on the back of the case. Classic Oyster closed case back design. The screw lock and leak-proof seal design provide the watch with better water and dust resistance. In terms of details, Clean is again extremely successful! On the movement side, the most powerful 4130 caliber is used. All functions can be operated. Some special movements do not use KIF shock absorbers to save costs, but in this movement, for the first time, the special edition KIF shock absorber, which is a very high-end mechanism shock absorber, has been applied in a replica movement. The three-layer base plate is produced entirely to the original factory standard, from the chamfer to the sun pattern. It is very close to the original in appearance. You can also distinguish the version of the watch through the mechanism. Using this type of 4130 in today's replica market is an assurance of quality!


On the belt side, this cement gray Daytona uses a rubber belt with a steel plate inside; The texture is nice and it is extremely comfortable when worn. It is also very easy to clean in the future. The harmony of gray and black rubber is extremely sporty. Perhaps this sporty style is one of the important reasons why this watch is popular.
Below are high resolution real shot photos of the Clean 4130 gray rubber Daytona; There will be an evaluation at the end of the article.







Evaluation: In this section, we briefly analyzed the Clean Rolex Daytona gray rubber model in terms of comparison with the original. In general, the workmanship of the watch is extremely good; Watch friends who like it can buy it with peace of mind.
I hope this article helps you. We will be sharing more detailed teardowns, live footage reviews, and real-replica comparisons in the future.
